DULERA vs NYSTATIN-TRIAMCINOLONE ACETONIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
DULERA is a combination of formoterol fumarate, a long-acting beta2-adrenergic agonist (LABA), and mometasone furoate, a corticosteroid. Formoterol acts by relaxing bronchial smooth muscle via beta2-receptor activation. Mometasone furoate reduces inflammation in the lungs by inhibiting inflammatory mediators and suppressing immune responses.
Nystatin is a polyene antifungal that binds to ergosterol in the fungal cell membrane, forming pores that cause leakage of intracellular contents and cell death. Triamcinolone acetonide is a corticosteroid that induces phospholipase A2 inhibitory proteins (lipocortins), thereby inhibiting the release of arachidonic acid and reducing prostaglandin and leukotriene synthesis, leading to anti-inflammatory, antipruritic, and vasoconstrictive effects.
Inhalation: 2 inhalations twice daily (morning and evening). Each inhalation delivers mometasone furoate 100/200 mcg and formoterol fumarate 5 mcg.
Apply topically to affected area twice daily for 2-4 weeks.

Formoterol: terminal half-life 10-14 hours (supports twice-daily dosing); Mometasone: terminal half-life 13.8 hours (range 10-20 hours) after inhalation.
Nystatin: negligible systemic half-life due to lack of absorption. Triamcinolone acetonide: terminal half-life ~2-5 hours (mean ~3.5 h) after intravascular administration; prolonged in hepatic impairment.
Formoterol: 10-15% renal as unchanged drug and metabolites, remainder hepatically cleared; Mometasone: >99% biliary/fecal as metabolites, <1% renal unchanged.
Nystatin: negligible systemic absorption; excreted unchanged in feces (~100%). Triamcinolone acetonide: metabolized hepatically; renal excretion of metabolites (~40%) and unchanged drug (<5%); fecal excretion (~60%).
